ENFORCER Access Control Power Supply, Five Outputs
4 SECO-LARM U.S.A., Inc.
a. Do not adjust the potentiometer unless absolutely necessary. Adjusting the potentiometer alters default factory settings.
b. The potentiometer adjusts the voltage of all output wire pairs. Check each device carefully. An output voltage in excess of
the specified voltage level of the device may cause damage.
15. Once the desired DC output voltage is achieved, connect the wire pairs to the device.
Programmable Features
a. AC-failure Relay Output Delay Timer — Program the AC-failure relay delay timer at 5sec, 5min or 5h using the DIP switch
(see "Overview," pg. 2). The default setting is at 5sec.
b. 2.2kΩ End-of-Line (EOL) Resistor — The end-of-line 2.2kΩ resistor for AC-failure relay and battery-failure / low battery
supervision relays (3A@24VDC) can be activated independently using the DIP switch (see "Overview," pg. 2, default ON).
c. Battery Presence and Low Battery Monitor —
When the LB MODE DIP switches are in the ON position, the power supply will
monitor the battery to verify if it has sufficient voltage to run the power supply in case of AC power failure. Selecting "OFF"
will stop monitoring of battery status and will charge battery continuously. It can take up to 5 minutes to alert you of a battery
failure. The length of time the system will run will be limited by the overall capacity and the age of the batteries and the
amount of load being drawn off the power supply.
16. Connect the backup battery to the backup battery terminal (see Fig. 2 and "Overview," pg. 2, default ON).
17. Close the enclosure door and secure it with either the provided machine screws or an optional cam lock.

Legend Functions Legend Functions
A E N To connect 110~240 VAC power ("A" for active
wire, "E" for earth or ground wire, and "N" for
neutral wire
TRIGGER Used to connect NO or NC input trigger signal (2.2kΩ EOL resistor)
from access control panel. A short or open circuit will transfer
power from "POS CLOSE LOOP" to "POS OPEN LOOP."
BAT.
FAIL
Used to notify battery failure. Dry contact relay
rated at 3A@24VDC. If backup battery is not
connected properly or if voltage output falls
below 11.2VDC for 12VDC setting (or 22.7VDC
for 24VDC setting, the connected warning device
will be activated.
VOL.
TRIGGER
Used to connect wet (5~30 VDC) input trigger signal from access
control panel. A short circuit or open circuit will transfer power from
"POS CLOSE LOOP" to "POS OPEN LOOP."
POWER FAIL Used to notify loss of DC power. Driy contact relay rated
3A@24VDC. If VDC input to the PDM is interrupted, the connected
warning device will be activated.
– BAT +
Used to charge the backup battery. Maximum
charging current is 5A
AUX OUTPUT
Used to activate other auxiliary device when trigger signal is
received from the "TRIGGER" or "VOL TRIGGER" terminals
